Replace canvas with @napi-rs/canvas

[beeing]

A suggestion for performance improvements.

Reviewing at the benchmark in https://www.npmjs.com/package/@napi-rs/canvas, this will be quick win for faster canvas replacement.

Thanks for your consideration.

If someone wanted to make a PR it would be great to test the difference. Is the platform support the same (macos/linux/windows)?

Due to Automattic/node-canvas#2448 this might also be required to avoid problems with recent node versions

As per the library intro, it is zero dependencies.

Also its still in pre-release and not fully supporting all functions yet as per Brooooooklyn/canvas#113

However, we can test it out first since the performance is much desirable.

I made the switch for a very small project. It was very seamless and immediately fixed a bunch of issues caused by node-canvas memory management bugs. YMMV but my experience with @napi-rs/canvas was fantastic.
